John Gill's Bible Commentary Ver. 9. Then the people rejoiced, for that they offered willingly , etc.] They were not only glad that they had it to offer, but that they had hearts to do it; they found themselves quite free to do the work, and saw it was so with others, which gave them extreme pleasure: because with perfect heart they offered willingly to the Lord ; not grudgingly, but cheerfully; not pressed and urged to it; not by constraint, but freely, and that with a pure view to the honour and glory of God: and David the king also rejoiced with great joy ; it made his heart glad exceedingly, now he was old, and just going out of the world, to see this good work in such forwardness, on which his heart had been so much set; it gave him reason to believe it would be set about in good earnest, be carried on with vigour, and brought to perfection.
Matthew Henry Commentary
Verses 1-9 - What is done in works of piety and charity, should be done willingly not by constraint; for God loves a cheerful giver. David set a goo example. This David offered, not from constraint, or for show; but because he had set his affection to the house of God, and thought he could never do enough towards promoting that good work. Those who woul draw others to good, must lead the way themselves.
